What map feature helps you plan routes around known construction zones?

• A. Street names only.
• B. Construction symbols, closures, detour arrows in the legend.
• C. Elevation contours.
• D. Scale bar.

Answer: (B)

Understanding how to plan routes around construction zones starts with reading the map legend for construction-related symbols. The legend shows construction symbols, closures, and detour arrows that indicate exactly where a road is affected, where a closure blocks passage, and what alternate routes are recommended. With this information you can proactively map a path that avoids the work zones, keeping you on open streets and maintaining faster response times.

Seeing construction symbols tells you which streets are impacted, while closures show you which paths are temporarily unavailable. Detour arrows point you toward suggested alternate routes, so you can adjust your plan before you reach the area. This makes navigation around ongoing work much more predictable.

Other map features mentioned don’t directly guide routing around work zones. Street names help you identify location but don’t tell you about closures or detours. Elevation contours relate to terrain and elevation changes, not traffic or road availability. The scale bar helps estimate distance, but it doesn’t indicate which roads are blocked or recommended detours.
